VAPR=BURNER.

SPECIFICATION forming part of Letters Patent No. 380.404, dated April 3, 1888. Application niet october 7, rsa1. seran No. 251,744. (No model.)

To @ZZ whom, iii may concern:

Be it known that I, Louis E. PIERPONT, a citizen of the United States, residing at Cambridge, in the county of Furnas and State of Nebraska, have invented new and useful Improvements in Vapor-Burners, of which the following is a specification.

My invention relates to improvements in vapor-burners; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a vertical sectional view of a vapor-burner embodying myimprovements. Fig. 2 is partly a top plan view ofthe same and partly a horizontal section.

A represents a cap which is screwed to the top of the staudpipe B by which the gasoline enters the generator. l

Crepreseutsa generator which is hemispherical in shape and is concave on its upper side, as shown. Formed in the upper edge of the said generator is an annular duct, D, which communicates with the upper end of the cap A on one side. A duct, E, formed in the generator communicates with the duct D at a point diametricallyopposite the cap A. This duct extends downward to the center of the generator, as shown.

F represents a vertical valve-seat, which is tubular in form and projects upwardly through a central opening in the bottom of the geuerator. This valve-seat communicates with the lower end of the duct E.

G represents a needle-valve which is screwed into the seat F. The said needle-valve has a stem, H, which extends downward below the generator for a suitable distance and is adapted to be turned in the valve-seat by means of a suitable handle or wheel attached to the lower end of its stem, so that the conical point ofthe valve may be caused to entirely close the conical opening in the upper end of the valve-seat, or to open the same to the desired extent.

I represents a clamping-nut which works on the threaded portion of the needle-valve below the tubular valve-seat, and is adapted to be screwed up against the lower end of the valve-seat, so asvto secure the needle-valve at any desired adjustment therein.

The needle-valve and its stem are provided with a vertical central bore or opening, K, which extends entirely throughlthe same,[and is thereby adapted to cause a current of fresh air to pass upward through the needle-valve and be discharged into the center of the generator from the point of the valve.

The operation of my invention is as follows: Initial heat is applied to the burner in the usual manner and the gasoline is caused to ow from the cap A through the ducts D and E in the generator to the tubular valves E F, and as the gasoline passes through the said ducts it becomes heated by contact therewith and vaporized and the vapor escapes upward through the opening in the upper end of the valve seat F surrounding the needle-point, where it is ignited. The constant current of fresh air which passes upward through the needle-valve is caused to commingle with the vapor at the point of the needle-valve, and thereby promote combustion. It will be seen that the air is thus supplied to the base of the flame at a point where it renders the combustion more nearly perfect, and hence a maximum proportion of the gas is consumed in the lame,and an economy ofthe gasoline isthereby effected.

Having thus described my invention, I claiml. A vapor-burner having the needle-valve provided with an opening which communicates with the outer air and extends to the point of the valve, for the purpose set forth, substantially as described.

2. The combination of the generator, the valve-seat therein, the ducts to supply vapor to the said valve-seat, and the needlevalve arranged in the valveseat and having the opening extending toits point,and thereby adapted to supply air to the base of the llame, substantially as described.

3. The combination, in a vapor-burner, of the generator C, having the valve-seatF at its lower side, and the ducts D and E,com municating with the stand-pipe, and the valveseat to supply vapor to thelatter, and the needle-valve arranged in the valve-seat and having the opening communicating with the outer air and extending to its point to supply air to the base of the flame, substantially as deA scribed.

In testimony thatI claim the foregoing as my own I have hereto affixed my signature in pres ence of two witnesses.

LOUIS E. PIEBPONI.
